truss    The research is focused on optimising long span roof structure (such as stadium and airport roofs) in terms of embodied carbon and cost. The optimisation is conducted for the permanent structure but the point of interest is to also include constructability and temporary works. The optimisation is conducted in three layered stages. The inner layer takes a given form and geometry and is used to optimise the structural elements using finite element analysis (e.g. cross sectional parameters). The second layer looks to vary the geometry, for example modifying the thickness of a truss. The third layer is for the overall form of the structure, for instance comparing using an arch with a cable and net structure.

     The objective of the project is to produce good practice guidelines that the industry can use when designing long-span roof structures. The focus is on producing a digital design process where software are interfaced together to produce a pragmatic optimised solution encompassing all the necessary constraints, outputting detailed drawings that can be used by industry. The objective is to design sustainably whilst still being able to produce a unique structure answering a unique set of requirements.
